For Teachers

This lesson is intended to take place over the span of five or six days, depending on your class. It can be condensed as needed to take up less time.

The resources provided here are not all-inclusive. Encourage students to find other sources of information to supplement their research when they have completed all the requirements of the lesson.

If time is a concern, consider using the final activity as the students’ assessment. It should demonstrate what the students have learned about the leafcutter ant. To check individual understanding, have each student write a few paragraphs explaining the different components of their group’s illustration and ask them to cite their evidence so that you can see their thinking.

Objectives

  • Students will understand the concept of social hierarchy and division of labor and how it applies to the leafcutter ant community.
  • Students will analyze how each ant role affects the function of the colony as a whole.
  • Students will evaluate the leafcutter system by making a claim about the importance of ant cooperation and supporting that claim using evidence.

Tips for Classroom Implementation

  • Ideally groups would be working in a computer lab. However, if computers are limited, explore the webpages as a class or provide printouts of the articles for each student.
  • For group work, assign each student with a specific task to ensure that they are given equal opportunity to participate and contribute to the group. Examples of group jobs could be a scribe, group monitor, materials monitor, and reader (if groups want to read aloud). Adjust positions as you see fit.
  • Make sure that the leafcutter relay is completed in a large flat area to avoid injury. Let the students know what they will be doing a day ahead of time so that they can wear appropriate shoes. 

Time Required

45-60 minutes a day for 5 days.

Classroom set-up

Arrange students so that they can easily work in groups of 3-4.

Each activity should be prepared with directions and all materials needed for the activities. Most printed materials can be found in the Experiment Packet [PDF].

Day 1 Materials

  • Leafcutter Ant Relay Instructions (in experiment PDF)
  • 1 computer per group or watch the video as a whole class
  • Notebooks
  • Pencils

Day 2 Materials

Day 3 Materials

Day 4 Materials

  • One copy of the Ant Anatomy coloring page per student (in experiment PDF).
  • Notebooks
  • Pencils
  • Dictionaries if extra support is needed

Day 5 Materials

  • Large construction paper or poster board for each group
  • Pencils
  • Coloring utensils

Ensure that you have access to computers for students to complete the Web activities. If computer access is limited then consider printing the online articles and webpages for your students to use. If you have access to a smart board or projector, then the video could be shown to the whole class.

Extensions

Challenge the students to research the infrastructure of the average city. What does almost every community have? (e.g., fire department, police station, grocery story, water supply, etc.)

Students can design a community for people that meet the four basic needs; water, food, shelter, and space.

  1. Does this community have a caste system?
  2. What does that look like?

Have students compare the superorganism of an ant colony to the body of an organism. Do any castes align with organ types or specific activities? Students can use a table to compare the functions of a colony and a body that are similar and how either a caste or an organ system or action handles that function.

Standards

Activity suggested for standards for grades 3 through 6.

  • PO 1. (Grade 3) Identify adaptations of plants and animals that allow them to live in specific environments.

Common Core Standards

Key Ideas and Details

CCSS.ELA-Literacy.RI.3.1: Ask and answer questions to demonstrate understanding of a text, referring explicitly to the text as the basis for the answers. Also good for grades in between 3rd and 6th.

CCSS.ELA-Literacy.RST.6-8.1: Cite specific textual evidence to support analysis of science and technical texts.

Craft and Structure

CCSS.ELA-Literacy.RI.3.4: Determine the meaning of general academic and domain-specific words and phrases in a text relevant to a grade 3 (or up to grade 6) topic or subject area.

Integration of Knowledge and Ideas

CCSS.ELA-Literacy.RI.3.7: Use information gained from illustrations (e.g., maps, photographs) and the words in a text to demonstrate understanding of the text (e.g., where, when, why, and how key events occur).

Range of Reading and Level of Text Complexity

CCSS.ELA-Literacy.RST.3 to 6-8.10 By the end of the year, read and comprehend informational texts at the appropriate text complexity band independently and proficiently. (Material can be modified for high end 3rd grade to 6th grade).

Next Generation Science Standards

  • 3-LS2-1: Construct an argument that some animals form groups that help members survive.
